MediaPlayer set negative rate problem

Hi, I am new to UE4.

I am trying to set up the blueprint to control the rate to reverse playing the video, but after I follow the documentation above, I found out that when I set the rate negative, it doesn’t reverse playing the video. In fact, it replays the video from the beginning again.
However, when I set the rate positive, it works correctly.
Does anyone know how did this happen and how do I solve this problem?
I really can’t find out the reason. Thanks!

To be more precisely, I first change the rate to negative value and the video stops playing. Then I change the rate back to 1, the video just replay it from the beginning. Playing forward works right, but when trying to play backward with negative rate, the video just paused.

Hi,

I have the same Problem!! Any advices?
